Water chiller HOFFMANN APPARATE

General description

Temperature control of coolant is necessary to meet the requirements for the high quality demanded by machine tool operators. Unwanted thermal fluctuations resulting from heating of the coolant must be prevented to minimize scrapped items during manufacturing.

HOFFMANN recirculation chillers maintain and cool the temperature of:
- drilling oils
- hydraulic fluids
- carrier oils
- emulsions
- water
- dielectrics
- and other fluids

Uses:
- Machine tools
- Hydraulic systems
- Tempering and anodizing baths
- Injection molding machines
- Plastics processing machines
- Vacuum systems
- Transformers
- X-ray systems
- Erosion machining systems, etc.

Our state-of-the-art chiller units are all charged with the R 134 a refrigerant that contains no CFCs. Only materials with low reaction levels are used for the components which come into contact with the liquid being cooled. Designs with air-cooled or water-cooled motor-driven compressors can be selected.

The electric control system is located in a fully enclosed, dust-tight IP 54 switchgear cabinet, containing all of the required switching, regulating and monitoring devices, including the adjustable contact thermometer. The entire system is completely wired and ready for connection to a 400 V, 50 Hz, 3 phase or 460 V, 60 Hz, 3 phase, PE (no neutral conductor required) power supply system. The design complies with all applicable regulations and codes for industrial equipment.
